i had some 3-yr-old delinquencies when i applied, my score was probably in the 650s, and i didn't realize til i reconned that i had miskeyed my salary. if i recall correctly, it was less than 10k salary that i input 
the rep approved me for 1k after i gave her my correct salary.
eta: didn't see your post about your actual income and question about how they know you work. they don't unless they ask for proof of income. i'd just give a good estimate of how much you make (800/month) and see what happens. be honest, though. i imagine that if they decline and you recon, they'd want proof since you're self-employed. barclays reps are really friendly and easy to work w, though.

^ This. There is no benefit in getting the Barclays Financing Visa (formerly Apple Rewards) unless you simply want a Barclays card to have one. This card no longer has rewards, just financing which is the same as a 12 month 0% APR card. If you are worried about not getting enough credit and need financing too, get a card from a lender with Intro 0% APR and willing to give a good credit line (like Discover).
If you want rewards I would then look into the Apple Card as it's 3% cashback if you buy at the Apple Store or website. Also, a bonus they will tell you your credit line before you accept the card. So you can avoid a hardpull if you don't like the limit and choose not to accept it.
